Application led September 17,1904. Serial No. 224.788. l

To all whom it may concern:

Be it known that I, CHARLES WVILLIAMS, a

citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful ImprovementsinMulticolorPresses, of which the following isa specification, referencebeing had therein to the accompanying drawing.

My invention has reference to printing presses and particularly relatesto certain improvements in the multi-color printing press for which Iobtained United States Letters Patent N o. 813,124, dated February 20,1906.

The invention consists of the combinations, arrangements andorganizations of parts hereinafter particularly described and thenpointed out inthe appended claims.

T o illustrate my invention I annex hereto seven sheets of drawings, inwhich- Figure 1 is a side elevation of the press, particularlyillustrating the Geneva-stop connections for imparting intermittentrotary motion to the platen frame and the means for rocking the shaft toadvance and retract the platens, and also the locking device for holdingthe fra-me against movement; Fig. 2 is a fragmentary view, )a rtially insection, of the slotted disk of the teneva-stop by means of which motionis communicated to the platen frame, the cam coperating with such diskalso being shown in section; Fig. 3 is a vertical section on the linea-a of Fig. 4; Fig. 4 is a front elevation of the press; F iv. 5 is avertical transverse section on the ine b-b of Fig. 1; Fig. 6 is a detailin section on the line c-c of Fig. 5 showing the platens at printingposition; Fig. 7 is a similar view y4o showing the platens in theirretracted positions; Fig. 8 is a plan view of one oil the platens andthe sheet grippers thereof; FJ 9 1s a side elevation of the sainelooking i. he direction of the arrow Fig. 8, and showing 45 the cams formoving the grippers to release i I I I the sheet; Fig. 10 is a verticaldetail section, on an enlarged scale, taken substantially on the sameline as Figs. 6 and 7, showing the positions of the platens at thedischarging and receiving points, and illustrating the relations of thecams for opening the grippers to release the sheet at the dischargingpoint and for closing the grippcrs at the receiving oint; Fig. 11 is adetail sectional view on the iine d-d of Fig. 8, showing one of theearns cooperating with a gripper to open the same and also to rock theplate 'for freeing the sheet from the platen; Fig. 12 is a plan view ofa chase showing the clamps thercon; Fig. 13 is a section'on the line e-eof Fig. al., illustrating the inking rollers and the relation thereto ofthe chase clamps, and also showing a platen; Fig. 14 is a side elevationof a fragment of the chase and .one of .the clamps, the chase beingbroken away to showone of the adjustable slides on which thc clamp ismounted; Fig. 15 is a pian view of the delivery fly; Fig. 16 shows thedriving connection for the iiy; and Fig. 17 is a perspective of the ilyboard.

Referring to Figs. 1 to, inclusive, the frame of the machine consists oftwo standards 20 and 21 which are suitably spaced apart and connected bycross members 22- located at the base of the standards. In the presentconstruction the standards and cross members are made of a singlecasting, although this is not material. Mounted on the standards is ashaft 23 the bearings of which are provided in the manner to beexplained. The shaft 23 has loosely mounted thereon a frame which in thepresent instance comprises a pair of spiders 24 which are spaced apartby cross bars 25, as shown in Fig. 5, the frame, comprising the spidersand cross bars being preferably an integral casting. The spider adjacentto the standard 21 is provided with a hub 26 which extends into abearing 27 in the Asaid standard, while the spider adjacent the standard20 is also provided with an extended hub 2S j ournaled in a bearing 29in the standard 2U. and 2S provide bearings for the shaft 23 and thelatter, as shown in Fig. 5, extends beyond the standard 20 as does alsothe extended hub 28. As shown in Figs. 1, 3, 6 and 7, the spiders 24have Iive equi-distant and symmetrical arms 3U and one of the cross barsis associated with and spaces apart each opposite pair of such arms. Inaddition to the cross bars 25 swinging yoke shaped platen supports 31are employed, one of which., as will be seen by reference to Figs. 4 and5, is journaled at its ends on bearing studs 32 on the out-er ends ofeach opposite pair of the arms 30. The supports 31 are The hubs 26 IGS-platen support 31.

substantially U-shapcd, and the widened central portion 33 of eachserves as a support for a platen 34.

Keyed to the shaft 23 between the spiders 24 are disks 35 each of' whichis provided with iive pair of equi-distant and symmetrical bearing ears36 at the periphery thereof, each pair of ears of each disk being alinedwith a pair of such ears on the other disk. Pivoted on pins 37 mountedon each associated pair of ears 36 are links 38 whose outer ends arepivotal ly connected, as at 39, to an associated hese disks 35 and links38 provide a toggle connection by means of which when the shaft isrocked the platens are moved outwardly, as the toggle connections arestraightened, to their printing positions, and are then returned orretracted.

Mounted on the standards 20, 21 are bed lates 40, upon which tlietypeVforms and inking mechanisms .iereinafter described are designed to bemounted. These bed plates in the present instance are separated byangular spaces of 7 2 degrees so that the )latens 34 will come inregister therewith as they are moved through intervals of 72 degrees,and as the press in the embodiment illust-rated is arranged for printingin three colors, three of such bed plates are shown to receive typeforms 41, 42 and 43.

In connection with each bed. plate 40 is a suitable inking mechanismsuch as that forming the subject matter of an application for UnitedStates Letters Patent filed by nic June 27, 1904, Serial No. 214,229',and which comprises, generally, suitable inkinur rollers 44 which areadapted to he moved azlong the type surface and then returned during theintervalsbetweenim pressions. These rollers 44 are carried by suitablechains 45 driven by sprocket wheels 46 mounted on shafts 4 7 suitablyjournaled on the. bed plates 40 and having motion communicated theretothrough the medium of segmental gears 48, fixed on shafts 49, alsosuitably journaled on the bed plates 4U, and meshing with inions 5() onthe shafts 47, as more fully exp ained in the application for patentlast referred to.

The late-ns 34, are designed to be rotated intermittently through aspace of 72 degrees, then moved outwardly for printing, and thenreturned or moved inwardly to permit of their being carried by therotation of the frame on which they are mounted to the next forms. Inthe present embodiment of the invention the intermittent movement oftheplatens is accomplished through the medium of the Geneva-stop mechanismnow to be described.

Referring to Figs. 1 and 5, the shaft 23 has keyed to its end beyond thestandard 20 a inion 51, and fixed to the extended end of thc hub 28 is aGeneva-stop disk or wheel 52 provided in the present instance with fiveperipheral recesses or slots 53. These slots,

as shown in Figs. 1 and 2, are disposed tangentially and aresymmetrical. Journaled on the side standards 20, 21, is a transverseshaft 53a which has iixed thereto a gear 54. This gear is provided onits inner face at diametrically opposite points with a pair ofcams whichtake the form ofpins 55. These pins during the rotation ofthe gear 54are brought in alternation successively into engagement with alternateslots of the disk 52 so as'to turn the disk at each half rotation of thegear through the necessary angle of 72 degrees to move the platenssuccessively into register with the forms 41, 42 and 43. The gear 54 isdriven by a pinion 56 fixed on a drive shaft 57 journaled on thestandards and provided witlithe usual fast and-loose pulleys 58. Thegear 54 turns in the direction of the arrow in Fig. 1, and as the pinenters the mouth of the slot in the path of the same it moves intoengagement with the wall of the slot so as to turn the disk. Byarranging the slots 53 tangentially the pins 55 enter the samesubstantially in the direct-ion of the length of the slots and engagethe walls of the slots at an acute angle, thereby avoiding the im actthat would otherwise result. The wall o the slot engaged b y the pin mayalso be provided vth a packing strip 59 of leather or other suitablematerial, seated in a recess in such wall and covered by a thin plate 60of metal, such as steel, to avoid wear, the strip 59. and plate 60 beingsecured in position by screws,

as shown in Fig. 2. The packing strip 59.

serves t0 deaden the noise as the pin engages the wall of the slot whenthe press is running athigh speed. Preferably the wall of the slotengaged by the pin is cut back as at 61,

so that the pin becomes disengaged from such wall before the end of the72 degrees movenient is reached, the momentum of the platen carryingframe serving to carry the platens to the limit of the requisite 72degrees movement, at which point the frame is engaged by the lockingdevice hereinafter described. By thus utilizing the momentum of themachine to complete the movement of the platens the action is renderedmore noiselcss and the imact which would otherwise result were the ramedriven positively to the point where it is arrested bythe lockingdevice, is eliminated.

The intervals in the periphery of the disk 52 between the slot-s 53 areconcave as showxi, and the gear wheel 54 is provided on its inner facewith iianges 62 concentric with the axis of such gear and located atopposite points between the pins 55, as clearly shown in dotted lines inFig. 1. These flanges are so disposed that'one of the same moves under a-concave portion of the disk 52 at the end of the movement of the platencarrying frame, and as the disk reaches the end of its movement suchconcave portion is concentric with the ange 62 the latter coperatingwith the IlV The co aeration of the parts in outwardly for printing.

Pivoted to the standard 20, as at 63 is an arm 64 provided at its freeend with a segmental rack 65 adapted to mesh with t-he pinion 51. Thisrack is rocked through the medium of a link 66 which is pivoted at oneend `to the arm 64 and at its other end to a crank pin 67 on the gear54.

The swing of the rack 65 is such that on both its forward and backwardmovement it moves into and then out of engagement with the pinion 51,and while in engagement therewith turns the same recess 69.

- an anti-friction roller 74.

through an angle of about 120 degrees, such movement being required toturn the shaft 23 far enough to thrust the platens out to their printingpositions and then return the same; and by means of the arrangementshown the shaft '23 is rocked, or moved forward and then back, at eachcomplete rotation of the gear 54.

As shown in Fig. 1, each of the arms 30 of the spider adjacent thestandard 20 is provided with an extension 68 having a tapering Pivotedto the standard 20, as at 70, is an arm 71 the free end of which extendsinwardly and is provided with a tapered toe 72 adapted to coperate withthe recesses 69. Also pivoted on the frame, on the pivot 63, is apresser bar 73 having at its free end an oil setwhich preferably takesthe form of A stem 75 passes freely through alined apertures in lugs 76on the arm 71 and bar 73 and is held in position by nuts 77 screwing onthe ends of the stem. Reacting between the lugs 76 and coiled about thestem 75 is an expansion spring 78. A transverse shaft 79 is journaled onthe standards and fixed to this shaft is a gear 80 Umm A.

which meshes with and is driven by the pinion 56, the said gear being sorelated to the gear 54 as to make two revolutions to each revolution ofthe gear 54, and one revolution to each backward or forward movement ofthe rack 65. Fixed to the shaft 79 inside the standard 20, as shown inFigs. 1, 3 and 4, is a cam disk 81, the major portion of whose peripheryis concentric with the shaft 7 9 but provided at a suitable point with adepression 82 providing a cam shoulder 83. The recesses 69 are sopositioned that the frame is locked by the mechanism described just asthe platens come into exact register with the type forms.

The sequence of movements is as follows: In Fig. 1 the platens are shownin their retracted positions. As the gear 54 turns continuously in thedirect-ion of the arrow one of the pins 55 thereof engages the slot 53in the path of the same thereby turning the disk 52 and consequently theplaten carrying frame forwardv or in the direction of the arrow Athereby moving the platens into register with the succeeding type forms.At the end of this movement the disk 52 is held against further rotationby the cooperation of one of the flanges 62 with the concentric concaveportion of the disk and the cam shoulder 83 engaging the roller 74 liftsthe bar 73 and, through the medium of the spring 7 S, thrusts thelocking toe 72 upwardly into engagement with the recess 69 which has bythe rotation of the frame been moved into position in the pat-h of thetoe. W'hile the disk 52 is prevented from rotating by the gear iange 62still, as the gear 54 continues its rotation there would be a tendencyto jar or vibrate the disk and consequently the platens. This isobviated by the locking device, as owing to the tapering formation ofthe tee and recess and by reason of the spring 7S the toe is wedgedtightly into the recess so 'as to lock the rotatable frame rigidlyagainst movement. Just as the frame is locked the rack 65, moving in thedirection of the' arrow B, Fig. 1, engages the pinion 51 and turns theshaft 23 forward in the direction of the arrow C, through an angle ofabout 120 degrees. At the end of the first half of this movement of theshaft the parts assume the positions shown in Fig. 6, the toggleconnections being straightened and thrusting the platens outwardly intoprinting position so that they coiperate with the forms as shown indotted lines in Fig. 3. The end half of the movement of the shaft breaksthe toggle joints and withdraws the platens into the positions shown inFig. 7. During this forward movement of the shaft 23, the concentricportion of the cam S1 moves past the roller 74 thereby holding the toeinv its locking position until the platens have been advanced andretracted, when the depression S2 comes under thc roller 74 permittingthe bar 73 and arm 71 to drop and withdraw the locking toe. The otherpin 55 now moves into engagement with the succeeding slot of the disk 52imparting a further forward movement to the platen frame and carryingthe platens to new positions, and at the end of t iis movement the frameis again locked by the toe 72, and the segmental rack G5 being movedbackward or in a direction reverse to that indicated by the arrow B,rocks the shaft 23 in the direction indicated by the arrow D, Figs. 1and 7, through an angle of 120 degrees. AS before the first half of thismovement straightens the toggles, moving the platens into the printingpositions, shown in dotted lines in Fig. 3 and also in full lines inFig. 6, the last half of the movement retracting the ICO platens to thepositions shown in Fig. 1,

when the lock is again released.

Any suitable means may be employed for feeding the paper to the presssuch as that shown in Figs. 1, 3 and 4 and `which forms the. subjectmatter of an application for patent filed by me June 27, 1904 andbearing erial No. 214,230. Briefly described such feeding mechanismcomprises the following construction. A suitable frame 84 is mountedupon the standards 20, 21, and has journaled thereon a transverse shaftS5 having keyed to one end a ratchet wheel 86. A. yoke 87 is looselypivoted on the shaft 85 and carries a pawl SS cooperating with theratchet wheel. The yoke 87 has an outwardly extending pin 89 to which ispivoted one end ot a pitnian 90 whose other end is pivotally connectedto a crank pin 91 secured to the shaft 79. Suitablv journaled on theframe S4 is a pair of feed rollers 92 and 93 designed to advance thepaper from the roll of paper 94. Motion is communicated to these rollersthrough the medium of a gear 95 fixed upon the shaft S5 and meshing witha pinion 06 on the adjacent end of the shaf t of the roller 92, t-heopposite ends of the roller sha-tts being provided with intermesliingpinions 97.

The roll of paper is carried by a sha-ft 9S saitably journaled on theframe S4. Suitabiy secured on the frame 84 in advance of and parallelwith thefeed rollers 02 and 93 is a stationary cutter blade 99 to one-end of which is pivoted, as at 100, a cut.-

ter blade 101. Fixed to the end of the blade 99 opposite the pivot otthe cutter 101, is an upstanding arm 102 to the upper end of which isattached one end of a contractile s ring 103, whose other end isattached to tlie. free end of the cutter blade 101, as shown in Fig. 4.This spring is designed to elevate the blade 101 after the cuttingoperation and to maintain the same in its normal elevated position.Pivoted on thel end of the blade 99, adjacent the arm 102, is a spindle104, to which is attached a lever 105 whose free end is provided with ananti-friction roller 106 adapted to enga-ge the upper edge of' thecutter blade 101 The end of the spindle 104 extends in advance of thecutter, as shown in Fig. 3, and has fixed thereto a tripping finger 107designed to be engaged by each platen, as it moves into position toreceive a sheet of paper, to operate the cutter to sever the sheet fromthe roll.

In order to prevent the lifting up of the rear edge and displacement ofa sheet upon the withdrawal of the cutter blade upon the severing of thepaper, I provide a sheet holder or clamp for holding the sheet until theplaten grippers, hereinafter described, have taken the sheet. Thisela-mp comprises a stationary plate 10S suitably secured to the underface of the blade 99 and a cooperating in vable plate 109 parallel with`Lhe plate 10S l and carried by a spring arm 110 secured to a lug 111mounted on the blade 99. Attached to the movable cutter blade 101 is aspring arm 112 which is bent in the present inst-ance i Y l clamp plate100 into engagement with the plate 10S. This action bends the spring 112and put-s it under tension to such an extent that upon the elevation ofthe cutter blade the end of' the spring continues to` hold the movable.clamping member in its.,-F cla-niping position until after the partialcleg vation of' the cutter blade and until thei' platen grippers gripthe sheet.

Suitably journaled on the frame 84 ati the rear of the feed rollers is ashaft 113` which is provided with a pair of toothed wheels 114 spacedapart a suitable distancc The. toothed wheels engage and reciprocate aIpair of strips 115 which are suitably supand one of which is shown inFig. 3.

ported on the frame and adapted to ieciprocate in advance of the, cutterand over the platen as shown in dotted lines in Fig. The shaft 113 isoscillated to reciprocate the strips 115 through the medium of asuit-1,: able train of gearing 116, shown in Fig. 3,

and deriving motion from a gear 117 fixed: One

on sleeve 11S loose on the shaft 85.

arm 110 of the yoke S7 is fixed to the sleeve i 11S. otisly in onedirection an intermittent rotary motion will, through the pawl and Theshaft 79 being driven continu-` ra tcliet mcchzinism, be. imparted tothe Shaft I 85, and this rotation will be transmitted and increasedthrough the gearing to the feed rollers and cause the paper strip to befed between such rollers a distance depending g on the throw of thecrank pin 01.

While an intermittent rotary motion is imparted to the shaft S5, owingto the attachment of the yoke arm 11S) to the loose sleeve 118, thelatter has imparted toit an oscillatory movement, thereby effecting,through the medium of the gear train 116 the reciprocating movement ofthe strips 115.

Referring to Figs. 8 to 11, it will be ohserved that the front and rearedges of each platen 34 is formed with a dovetailed groove 120 in whichis slidably mounted at each end the complementary shaped iib 1.21 formedon a vertical plate 122. The pair ot plates 122 at each end of theplaten are provided at the out-er and upper corners with upstanding ears123 and pivoted in these ears and extending across the platen is agripper 124. The grippers are pivoted by means of outwardly extendinglugs 125. Fixed to each gripper 124 beyond one edge of the platen is anarm 126 and the arms of each pair of grippers associated with the platenextend in opposite directions, as shown in Fi 8 and 9. At tached to theupper end o each arm 126 in advance of the pivot of its gripper is acontractile spring 127 whose other end is attached to an extension 12Sformed on the plate 122. W hen the gri per is moved on 1ts pivot theupper end o the spring 127 is carried past the center of oscillation,thereby holding the bar in its raised position, such position beingdefined by a stop 129 fixed to the plate 122 and engaged by the arm whenthe bar is raised. The pivot lugs 125 of each gripper are provided withaxial openings (not shown) into which extend the pivots 13() (shown indotted lines in Fig. 8) of a blade 131 which, as shown in Fig. 8,extends across the platen and rests upon the latter under the gripper124, as shown in Fig. 11.

Each blade 131 is rovided at its end adjacent the arm 126 or theassociated gripper, with a rearwardly extending finger 1 32. Theopposite sides of the platen on the under face of the latter areprovided with recesses 133, as shown in Fig. 11, adapted to be engagedby pins 134 slidably mountedin lugs 135 formed on the inner face of eachextension 128. Coiled about each pin is an expansion spring 136 whichreacts against the lower lug 135 and a shoulder 137 formed on the pin134. These springs 136 force the pins into engagement with .the recessesand hold the slide plates 122 in ad'usted positions. By disengaging thepins grippers together with the blades 131 may be adjusted along theplaten in accordance with variations in the size of the sheets beingdelivered to the platens. Mounted on the standards 20 and 21 in advanceof the paper feeder and extending transversely of the press is a bar 138(Figs. 3 and 4) on which is adjustably secured a air of trips or camsspaced apart on the liar so as to co-operate with the arms 126 when thegrippers are in their open positions and close the same on the sheetafter the latter is delivered to the platen. These cams are constructedas shown in Figs. 4, 9 and 10, consisting of brackets, 139, secured onthe bar 138 by screws 140 and having inwardly extending toes 141 whichwhen the grippers are in the dotted lines position Fig. 9, and theplaten is moved outwardly at the feeding ltpoint are engaged by theinclined faces 142 o the arms 126 so as to move the grippers on theirpivots to grip the sheet.

Each platen, as the platen carrying frame is intermittently rotated,advances from the feeding point to the type forms in succession andafter receiving an impression finally from the form 43, at the nextintermittent rotary motion is advanced to the discharge point and as theplatens are moved outwardly to printing positions discharges its sheet.This discharge is accomplished by the following means: Attached at itsends to the standards om the recesses the 20 and21 at the dischargepoint, is a cross bar 143, Figs. 1, 3, and 11, on whichis adjustablysecured, (as by set-screws, one of which is shown in Fig. and designated144,) apair of brackets 145. Each bracket is provided with a shoulder146 and a toe 147 extending beyond the shoulder, as shown in Figs. 10and 11, and as the platen is moved outwardly into printing position atthe discharge point, the arms 126 engage the shoulders 146 and after thegrippers are moved far enough to release the sheet the fingers 132 oftheblades 131 come into engagement with the toes 147 thereby rocking theblades on their pivots and lifting the edges of the sheet from theplaten, so as to free the sheet in the event that the latter adheres tothe platen, the sheet then sliding down the inclined face of the platenon to the fly 148. The grippers are turned far enough to threw thesprings 127 past the pivots of the grippers so that they remain in theiropen positions until closed by the closing cams at the feeding point,but the blades 131 as soon as the platens 'are withdrawn preliminary tobeing ad.- vanced to the next point, fall by gravity so as to rest onthe platen as shown in Fig. 1 1.

The operation of the press in connection with the feeding and dischargeof the sheets will now be understood. As each platen is being advancedto printing position at the feeding point, a strip of paper is fedforward by the feeding rollers 92 and 93 together with and resting onthe paper supporting strips 115. Just before the platen reaches theoutward limit of its movement, the strips 1 15 are retracted permittingthe sheet to rest on the platen and also at its side edges on the blades131. As soon as the strips 115 have been withdrawn, the platen engagesthe finger 107 actuating the cutter blade 101 to sever the sheet, theclamp plate 109 holding the out edge of the latter to maintain the samein position on the platen until the grippers 124 take the same. Duringthe end of the outward movement of the platen the cam toes 147 areengaged by the beveled faces 142 of the gripper arms, thereby closingthe grippers against the sheet. 'lhe platen is then retracted and as itbegins to .nove inwardly the finger 107 is released permitting thespring 103 to elevate the blade and release the clamp 1.09. Afterreceiving an impression from each type form, the platen finally reachesthe discharge point and as it is moved outwardly to printing position,the grippers are opened by the cam shoulders 146 and then the sheet isfreed by the blades 131 as heretofore described.

A suitable delivery mechanism is shown in Figs. 1, 3, 10, 15, 16 and 17.As shown in Figs. 3, and 16, the iiy 14S, consists of suitable fingersfixed to a bar 149 carried by the hub 15() of a segmental gear 151 whichis loosely mounted on the shaft 49 of the inking IOO IIO

mechanism associated with the printing form 43. The gear 151 isoscillated by Va segmental gear 152 fixed to the shaft 47 of the sameinking mechanism, and the movement of the gears is so timed as topresent the fly to the platen, as shown in Fig. 10, as the sheet slidesfrom the latter. Extending outwardly from the frame of the press, Figs.3 and 17, are brachets 153 supporting a pair of suitably `spacedparallel bars 154 from which the J1y board 155 is hung. This fly boardis provided with a pair of rods 156, one located near each end of thesame, and attached to the ends of the rods 156 are the lower ends ofcoiled springs 157 whose upper ends are attached to the bars 154. Bymeans of this arrangement the fly board is held in proper posi-tion withrelation to the Hy and gradually sinks by gravity as the sheetsaccumulate thereon, owing to the yielding of the springs, so that thatrelation is constant.

In connection with the grippers of the platens, I preferably employauxiliary clamping devices which are associated with the type forms andadapted to cooperate with the platen grippers to hold the sheet, whilethe impression is being made, at all four of its edges. Referring toFigs. 12, 13 and 1-1, it will be observed that the chase 15S is providedwith a groove 159 at each side. Located in the rooves are slides 160adapted to be held in a( justed positionby set screws 161. Pivotallylnounted on each opposite pair of slides 160 and extending across thechase is a clamp 162 provided with an in wardly extending offset portion163. Fixed to each end of each clamp is a finger 164, the

fingers of each clamp extending away from those of the other clamp.Attached to each finger 164 is a leaf spring 165 whose free end restsupon the chase and which tends to hold the clamps depressed. The inkingrollers 44 do not interfere with the clamps 162 as they travel back andforth over the type, as their cores 166 are reduced so as to clear thefingers 164, as shown in dotted lines, Fig. 13.

The operation of the chase clamps, which by reason of the adjustabilityof the slides 160, may be adjusted in accordance with variations in thesize of the forms, will be ap- I parent from Fig. 13. As the platen isthrust outwardly against the type, it engages the fingers 164 rockingthe clamps 162 on their pivots so that they press the front and rearedges of the sheetirmly against the platen, thereby preventing the sheetfrom sagging at such edges and being smeared. The other edges of thesheet are of course held by the laten grippers so that during the timeof the lmpression the sheet is clamped at all four of its edges. As theplaten is retracted the clamps 162 are returned to their originalpositions.

Having described my invention, what I claim, and desire to secure byLetters Patent of the United States, is-
